CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 564,186, dated July 21,1896.

` Application led May 17,1895. Serial No. 549,643. (No model.)

To @ZZ whom it may concern:

Be it known that I, J osEPH H. DIoKINsoN, a citizen of the UnitedStates, and a resident of Brooklyn, in the county of 'Kings and State ofNew York, have invented certain new and useful Improvements in ConveyingApparatus, of which the following is a specification.

My present invention is particularly useful for the purpose of conveyinglogs in logging and enables me to dispense with much of the apparatusheretofore deemed indispensable, and thus to simplify the apparatus andreduce its cost.

In the accompanying drawings, Figure 1 represents a side view 01": theapparatus in use. Fig. 2 is a detail showing a construction wherein theupper portion of the carriage is omitted. Fig. 3 is a detail showing theform of carriage of Fig. 1 enlarged.

1 is a rope-drum engine containing the drums 2 and 3.

#1 and 5 are head and tail supports, which may be trees, masts, ortowers.

6 and 7 are sheaves secured at a sufficient elevation to thehead-support.

8 is a sheave secured at a sufficient elevation to the tail-support.

9 is a carriage.

10 11 is a rope extending from the drum 2 over the head-support sheave 6around the tail-support sheave 8 and back to the carriage 9, to whichits end is made fast.

12 is a rope extending from the drum 3, over the head-support sheave 7and the sheave 13 of the carriage 9, and thence to the log 14,

to which its end is made fast by the chain 15.

3y the use of the parts already described, a log may be conveyed fromalmost any point between the head and tail supports to the head-support,as follows: By paying out on the rope 12 and hauling in on the rope 10the carriage 9 can be carried out the requisite distance toward thetail-support 5 to enable the chain 15 to be made fast to a log, as, forinstance, to the point shown in Fig. 1. Thereupon the chain is made fastto the log and the drum 3 is turned so as to haul in on rope 12, and thedrum 2 is either held stationary or turned so as to haul in on the rope10 1l,

until the carriage 9 has been lifted a proper distance from the groundto avoid obstructions. Then the rope 12 is hauled in and the rope 10 11is paid out at such a relative speed as to carry the carriage and thetrailing log toward the head-support while maintaining the carriage atsubstantially a constant elevation. If an obstruction is niet higherthan ordinary, the end of the log can be lifted over it either bystopping drum 2 and continuing to run drum 3, or by stopping drum 3 andrunning drum 2 backward, so as to haul in instead of pay out on rope 1011. The drums 2 and 3 constitute a form of two inversely moving haulingdevices for giving the ropes the mode of operation above described.

I prefer that the carriage should be in the form shown in Figs. 1 and 3,being extended upwardly above the sheave 13 into the ineinber 16, whichcarries the sheaves 17 and 18. The rope 10 is so guided as to run underthese sheaves 17 and 18, so that the ropes 10, 11, and 12 are allconnected by the member 16 at the point where the log is suspended.vThis gives a better control land throwsa portion of the verticalsupport upon the rope 10.

I claim- 1. In a conveying apparatus, in combination, twoinversely-moving hauling devices, as the drums 2 and 3, head and tailsupports, a carriage, as 9, a sheave on the same, arope connected at oneend with one of said hauling devices and extending over saidtail-support and back again to said carriage with which its other end isconnected, and another rope extending from the other of said haulingdevices over said head-support at an elevation and over saidcarriage-sheave, substantially as described; whereby the carriage israised and conveyed by the conjoint action of said hauling devices, asset forth.

2. In a conveying apparatus, in combina tion, two inversely-movinghauling devices,

as the drums 2 and 3, head and tail supports, a carriage as 9, a sheaveon the saine, arope connected at one end with one of said haulingdevices and extending over said head-sup` port and over saidtail-support and back again to said carriage with which its other end isconnected, another rope extending from the scribed; whereby the carriageis raised and other of said hauling devices over the heztdconveyed bythe conjoint action of said 112mb support at substantially the sameelevation ing devices, as set forth.

as the rst-nmned rope and over said ozuriage- JOSEPH H. DICKIN SON. 5sheave and means, as the shezwe 17, connected XVitneSSes:

with the carriage and resting on the body of J. EDGAR BULL,

said first-:named rope, substantially as de- M. VILSON.
